Affogato-Style Frappuccino This one probably classifies more as an in-the-know drink than a "secret" one. Order any Frappuccino "affogato-style" and you'll get a shot of hot espresso added on top of your drink as opposed to having it blended in.
Healthy Homemade Pumpkin Spice Latte: And again, because this is a fall staple, we had to add another PSL. This version is made with unsweetened vanilla almond milk and pumpkin pie spices. Check out the recipe at Eating Bird Food.
